How we got 7.5 ShowHide
Rates 8.7/10 on the rest of its formulation — the cap is a targeted caution, not a problem with the whole product.
Methodology v3.1 (updated 8 Oct 2026) — what changed
This bathing bar effectively cleanses and delivers 2.5% Benzoyl Peroxide, an active ingredient for acne treatment. However, the presence of undisclosed 'Fragrance' means specific allergens are not listed, which is a concern for individuals with sensitive skin or fragrance allergies. The soap noodle base provides a traditional cleansing action, but its alkaline nature can be drying for some skin types.

Fragrance
"Fragrance" or "parfum" is a catch-all term that can conceal a blend of hundreds of undisclosed chemicals, including known allergens, sensitisers, and potential endocrine disruptors. The EU now mandates disclosure of 82 specific fragrance allergens. People with fragrance sensitivity, asthma, or contact dermatitis should prefer fragrance-free products.

Contains 'Fragrance', an undisclosed mix of chemicals that can be a common allergen. Individuals with sensitive skin or fragrance allergies should exercise caution.
Claim check
Front-of-pack marketing claims checked against this product's actual ingredients and nutrition. "Can't verify" means the label does not provide enough information to check the claim — it is not the same as the claim being false.
The claim refers to the product's formula being the same, which cannot be verified from the provided ingredient list alone.
The claim refers to a new visual appearance, which cannot be verified from the provided ingredient list.
Benzoyl Peroxide is listed, but the label does not state the 2.5% concentration, so the strength cannot be confirmed.
The claim states the product helps control acne, which is a functional benefit that cannot be verified from the ingredient list alone.
Benzoyl Peroxide is listed as the first ingredient, confirming its presence in the soap.

About this analysis: Based on declared label information and available evidence. Decode Label does not independently laboratory-test products, and a score is not a regulatory determination or medical advice.
Disclaimer: Safety scores are Decode Label-generated assessments based on publicly available regulatory data (FSSAI, WHO, EFSA, IARC) and peer-reviewed research. They are not a substitute for professional medical advice, and they are not a regulatory determination, a laboratory safety certification or a medical diagnosis. Ingredient safety can vary by individual health conditions, concentration, and usage context. Decode Label is an independent information service and scores every brand by the same rules. No brand pays for or influences its score. Our founder also founded the personal-care brand Botani Bestie (see our story); its products are scored exactly like everyone else's. Data limitations: This assessment is based on the information declared on the product label and the evidence sources above — Decode Label does not independently laboratory-test this product. Ingredient concentrations, sourcing and manufacturing can vary between batches and are not always disclosed. A finding that is not shown here means it was not identified from the available label information, not that it has been ruled out.
